I'm not aware of any conclusive determination. Can you post a photo of your HBG? If you obtained them locally, they could be either one (BG or CNBG)

Did you stock these HBG yourself? Might you inquire about their lineage at the hatchery they came from?


"Forget pounds and ounces, I'm figuring displacement!"

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
